9: Calibrating the 
appropriate speaker 
settings automatically 
(Auto Calibration)
The DCAC (Digital Cinema Auto Calibration) 
function allows you to perform automatic 
calibration, such as checking the connection 
between each speaker and the receiver, 
adjusting the speaker level, and measuring the 
distance of each speaker from your seating 
position automatically. Refer also to “Quick 
Setup Guide” supplied with the receiver.
Before you perform the Auto Calibration, set 
up and connect the speakers (page 14).
• The AUTO CAL MIC jack is used for the 
supplied optimizer microphone only. Do not 
connect other microphones. Doing so may 
damage the receiver and the microphone.
• During the measurement, the sound that 
comes out of the speakers is very loud. The 
volume of the sound cannot be adjusted. Pay 
attention to the presence of children or to the 
effect on your neighborhood.
• Perform the measurement in a quiet 
environment to avoid the effect of noise and 
get a more accurate measurement.
• If there are any obstacles in the path between 
the optimizer microphone and the speakers, 
the calibration cannot be performed 
correctly. Remove any obstacle from the 
measurement area to avoid measurement 
error.
• When you use a bi-amplifier connection, set 
“BI-AMP Speaker” to “ON” in the Speaker 
settings menu before you perform Auto 
Calibration.
